Image Description and Details :

This nebula was first discovered by the astronomer Stewart Sharpless in 1959 who included it in his catalogue of HII regions under the name of Sh2-200. In 1983, Sh2-200 was included in the HDW catalogue of possible planetary nebulae by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. However it wasn't confirmed to be a true genuine planetary nebula until 2017 when spectra was taken as part of professional observations. In 1987, further narrowband observations by Herbert Hartl and Ronald Weinberger detected a large faint outer halo extending further than the central shell.Imaging telescopes or lenses: Takahashi FSQ130EDImaging cameras: QSI 6120iMounts: Takahashi EM 400 Temma 2Guiding cameras: QHY CCD QHY 5 IIDates: Nov. 22 - Dec. 12, 2020Frames:Astrodon Ha 5nm: 45x1200" Astrodon OIII 5nm: 45x1200"Astrodon RGB: 3x30x120" Integration: 33 Hours
